An inclined truss supports three forces at joints along the left edge, as shown in the figure below. The forces have magnitudes F₁ = 1.5 kN, F2 = 5.5 kN, and F3 = 7.5 kN. The lengths for all horizontal members is s = 3.5 m and for all vertical members is h = 3 m. The truss is held in equilibrium by a pin at point A and a roller at point F. Use the method of sections to determine the force in members BD, CD, CE, AC, and BC and indicate whether they are in tension or compression. Note: Express tension forces as positive (+) and compression forces as negative (-). B S F₂ S F3 PBD = number (rtol=0.01, atol=1e-05) kN PCD = number (rtol=0.01, atol=1e-05) kN ? PCE = number (rtol=0.01, atol=1e-05) kN ? PAC = number (rtol=0.01, atol=1e-05) kN PBC = number (rtol=0.01, atol=1e-05) kN S
